Abstract

A closure for a container which comprises a cap ( 1 ) and a locking ring ( 2 ), the cap being adapted in use to sealably engage the opening ( 3 ) of the outlet neck ( 4 ) of a container ( 5 ); and the locking ring being adapted in use to be mounted over the outlet neck of the container and slidable between first and second positions, such that in use in the first position, the locking ring engages the cap and thereby prevents disengagement of the cap from the opening of the container and in the second position, the locking ring is (a) disengaged from the cap thereby allowing the cap to disengage the opening of the outlet neck and (b) retained in the second position on the outlet neck of the container.

Claims

exact text as granted — not AI-modified
1 . A closure for a container which comprises a cap and a locking ring; the cap being adapted in use to sealably engage the opening of the outlet neck of a container; and the locking ring being adapted in use to be mounted over the outlet neck of said container and slidable between first and second positions, such that in use in the first position, the locking ring engages said cap and thereby prevents disengagement of said cap from said opening of said container and in the second position, the locking ring is (a) disengaged from said cap thereby allowing said cap to disengage the opening of said outlet neck and (b) retained in the second position on the outlet neck of said container.  
   
   
       2 . A closure as claimed in  claim 1  in which, the cap has a screw thread which in use, co-operates with a corresponding screw thread on the outlet neck of the container.  
   
   
       3 . A closure as claimed in  claim 1  having one or more co-operating locking lugs and recesses to engage the locking ring and cap.  
   
   
       4 . A closure as claimed in  claim 3  in which the cap has one or more locking lugs which are adapted to engage corresponding locking recesses of the locking ring and/or the cap has one or more locking recesses which are adapted to engage corresponding locking lugs of the locking ring.  
   
   
       5 . A closure as claimed in  claim 4  in which the cap has a tubular part which in use, engages the neck of the container and the cap has locking recesses in the form of longitudinal slots in the tubular part.  
   
   
       6 . A closure as claimed in  claim 1  in which the cap is manufactured of one or more plastics materials.  
   
   
       7 . A closure as claimed in  claim 6  in which the cap is manufactured from a thermoplastics material and a thermoplastic elastomer material.  
   
   
       8 . A closure as claimed in  claim 6  in which the cap is manufactured from more than one plastics material by sequential co-injection moulding.  
   
   
       9 . A closure as claimed in  claim 1  in which the locking ring has one or more, typically 2 to 24, preferably 2 to 8, for example 4 or 6, outer lugs by which it may be slid from the first to the second position thereby disengaging it from the cap and allowing the cap to disengage the opening of the outlet neck.  
   
   
       10 . A closure as claimed in  claim 1  in which the locking ring is adapted to be retained in the second position by one or more co-operating retaining lugs and retaining recesses.  
   
   
       11 . A closure as claimed in  claim 10  in which the locking ring has one or more retaining lugs which are adapted to engage corresponding retaining recesses of the outlet neck of the container and/or the locking ring has one or more retaining recesses which are adapted to engage corresponding retaining lugs of the outlet neck of the container.  
   
   
       12 . A closure as claimed in  claim 11  in which the locking ring has retaining lugs and/or retaining recesses on a flexible part of the ring, which when the locking ring is slidably moved into the second position flexes to allow the retaining recesses and corresponding lugs to engage, hereby retaining the locking ring in the second position.  
   
   
       13 . A closure as claimed in  claim 1  in which the locking ring is manufactured of one or more plastics materials.  
   
   
       14 . A container with a closure as claimed in  claim 1 .  
   
   
       15 . A container as claimed in  claim 14  whenever containing liquids such as lubricating oils, especially automotive lubricating oils, for example hydrocarbon or synthetic lubricating oils.  
   
   
       16 . A container as claimed in  claim 14  whenever containing liquids such as fuel additives, anti-freeze compositions, brake fluids and the like.  
   
   
       17 . A closure as claimed in  claim 4  in which the locking ring is adapted to be retained in the second position by one or more co-operating retaining lugs and retaining recesses.  
   
   
       18 . A closure as claimed in  claim 17  in which the locking ring has one or more retaining lugs which are adapted to engage corresponding retaining recesses of the outlet neck of the container and/or the locking ring has one or more retaining recesses which are adapted to engage corresponding retaining lugs of the outlet neck of the container.  
   
   
       19 . A closure as claimed in  claim 18  in which the locking ring has retaining lugs and/or retaining recesses on a flexible part of the ring, which when the locking ring is slidably moved into the second position flexes to allow the retaining recesses and corresponding lugs to engage, hereby retaining the locking ring in the second position.  
   
   
       20 . A closure as claimed in  claim 9  in which the locking ring is adapted to be retained in the second position by one or more co-operating retaining lugs and retaining recesses.  
   
   
       21 . A closure as claimed in  claim 20  in which the locking ring has one or more retaining lugs which are adapted to engage corresponding retaining recesses of the outlet neck of the container and/or the locking ring has one or more retaining recesses which are adapted to engage corresponding retaining lugs of the outlet neck of the container.  
   
   
       22 . A closure as claimed in  claim 21  in which the locking ring has retaining lugs and/or retaining recesses on a flexible part of the ring, which when the locking ring is slidably moved into the second position flexes to allow the retaining recesses and corresponding lugs to engage, hereby retaining the locking ring in the second position  
   
   
       23 . A closure as claimed in  claim 1  in which the locking ring is manufactured of one or more plastics materials.
